Description
  • OXYGEN FREE COPPER (OFC) - Our primary cable OFC wire is the most economical option for choosing power or ground wire and is a great conductor of power. Oxygen Free Copper gives you an economic power cable with excellent power transfer. Systems that require more power should use OFC cable wiring.
  • POWER / GROUND WIRE SET - Our bundled power wire set is great for a car amplifier or subwoofer or to be used as a ground wire on your electric wire installs. Use for many different applications such as indoor lighting, car radio, automotive, lighting, car speakers, power cables, 12v power inverter, ground wire, or welding cable.
  • SOFT TOUCH JACKET - Soft touch jacket design designed for the electrical and auto repair installer in mind. Strong, yet durable PVC jacket that is best for indoor use but has flexibility, elasticity, and impact resistance built in.
  • EASY POLARITY IDENTIFICATION - Easy color coded ground wire helps with installation to let you know which cable should connect to the terminal. Making a polarity error could cause serious damage to your audio equipment.
  • WIDE COMPATIBILITY - Also known as power wire, ground wire, trolling motor wire, automotive wire, speaker wire, car radio wire, amp wire, electrical wire, or welding wire designed for up to 300v voltage. We have many gauge wires to choose from, such as 1/0awg, 4awg, 8awg with black, red, blue wire color options and 25ft, 50ft lengths

Why GEARit

Built to work. Built to last.

99.99% Pure Copper

OFC vs Copper Clad Aluminum

99.99% Pure Copper

Solid oxygen-free copper strands carry current with lower resistance than aluminum-core CCA wire, for stronger power delivery to amps and accessories.

Current Through the Whole Conductor

Less Heat, More Usable Power

Current Through the Whole Conductor

In OFC wire, current flows evenly through the entire copper core instead of only a thin copper plating, which helps reduce voltage drop over long runs.

One Wire, Many Jobs

Car Audio, RV, Marine, Solar and More

One Wire, Many Jobs

Use it for amplifier power and ground, Big 3 upgrades, inverters, winches, off-grid solar banks and heavy equipment.

Oxygen-Free Copper

Oxygen-Free Copper

True 4 AWG oxygen-free copper for improved conductivity and reduced oxidation over time.

Soft-Touch Flexible Jacket

Soft-Touch Flexible Jacket

The flexible jacket bends easily around engine bays, firewalls and trim panels for faster, cleaner installs.

Excellent strand count!

This wire is excellent quality. It has a very large strand count, decent insulation that’s very flexible, and is pure copper, plus you can’t beat the price!

NOT BLACK COLOR

“Black” wire is brownish, not solid black color as expected… change info on site that your wire products appear brownish.

Good value, high quality wire

This wire is durable, the insulation is thick and flexible, and since it's stranded the wire is flexible and easy to work with. The insulation is thick enough to offer good protection, and the texture of the insulation is somewhat smooth, which makes working with it a little bit easier. With the amount of copper, and the overall cable quality, this is a nice value considering the high cost of copper. The total thickness (including insulation) is about 10mm.

It’s not black it’s dookie brown

First of all they advertise it on this nice roll of thick heavy duty black power wire. But what they send you is a ball of dookie brown and very cheap power wire. It’s absolutely hideous!

Perfect wire

Wire is very flexible for 4awg and in my opinion is the cheapest good wire on the market, started using it for amp wiring and have had no issues at all, thickness was perfect for fitting into tight spots too, not as bulky as 1/0

Nice internal copper strands.

It is real copper and high strand. Used this for car audio amplifiers And happy with it. I am honestly not sure how long the outer insulation would last in the harsher under-hood environment though.

Good quality OFC cable!

This was long enough to go the "long way" around the engine from the battery, through the firewall, to the back of my SUV.

Best price OFC wire

Great flexibility, using to connect 30Kw of LiFePo4 batteries to a 48v inverter. Real copper is the only way to go, and this has lots of fine copper strands. Great for anything high amperage. I’ve bought all different sizes from GearIt and everything exceeds my expectations.

Great Primary for Auto Sound

Really good wire for auto sound power installs. Better that the stuff you can get in install packages and way more length for those really long run jobs. Worth it! I've used both the 8ga and this 4ga. It's easy to work with and well insulated.

Best value I could find on OFC wire.

4G, 25' RED OFC wire, the GOOD stuff. Worked very well for adding 1000 watt JL mono to 22 Ram 1500. I had enough to do power, and, with some black shrink tube, the ground as well.

Flexible and good looking

Used this to rewire my truck and install a remote battery kill switch. Very happy with the results
